关于 c# WPF 怎样用一个button来控制4个柱子

private void button2_Click(object sender, RoutedEventArgs e)
{
DateTime startTime = DateTime.Now;
BubbleSort(array);
SelectionSort(array);
InsertionSort(array);
ExchangeSort(array);
ShellSort(array);

TimeSpan diff = DateTime.Now.Subtract(startTime);
executionTime = diff.TotalMilliseconds;
MessageBox.Show(executionTime.ToString());

//BubbleSirt
Rectangle rectBubbleSirt = new Rectangle();
rectBubbleSirt.Width = 10;
rectBubbleSirt.Height = executionTime;
rectBubbleSirt.Fill = Brushes.Yellow;
rectBubbleSirt.Stroke = Brushes.Blue;
Canvas.SetLeft(rectBubbleSirt, 10);
Canvas.SetBottom(rectBubbleSirt, 50);
canvas.Children.Add(rectBubbleSirt);

//InsertionSort
Rectangle rectInsertionSort = new Rectangle();
rectInsertionSort.Width = 10;
rectInsertionSort.Height = executionTime;
rectInsertionSort.Fill = Brushes.Yellow;
rectInsertionSort.Stroke = Brushes.Blue;
Canvas.SetLeft(rectInsertionSort, 50);
Canvas.SetBottom(rectInsertionSort, 50);
canvas.Children.Add(rectInsertionSort);

//SelectionSort
Rectangle rectSelectionSort = new Rectangle();
rectSelectionSort.Width = 10;
rectSelectionSort.Height = executionTime;
rectSelectionSort.Fill = Brushes.Yellow;
rectSelectionSort.Stroke = Brushes.Blue;
Canvas.SetLeft(rectSelectionSort, 100);
Canvas.SetBottom(rectSelectionSort, 50);
canvas.Children.Add(rectSelectionSort);

//ShellSort
Rectangle rectShellSort = new Rectangle();
rectShellSort.Width = 10;
rectShellSort.Height = executionTime;
rectShellSort.Fill = Brushes.Yellow;
rectShellSort.Stroke = Brushes.Blue;
Canvas.SetLeft(rectShellSort, 150);
Canvas.SetBottom(rectShellSort, 50);
canvas.Children.Add(rectShellSort);

//ExchangeSort
Rectangle rectExchangeSort = new Rectangle();
rectExchangeSort.Width = 10;
rectExchangeSort.Height = executionTime;
rectExchangeSort.Fill = Brushes.Yellow;
rectExchangeSort.Stroke = Brushes.Blue;
Canvas.SetLeft(rectExchangeSort, 200);
Canvas.SetBottom(rectExchangeSort, 50);
canvas.Children.Add(rectExchangeSort);
}
现在的问题 这5个柱子的值都是一样的，要怎么改才可以button2来控制5个柱子让得到自己的值

Answer 1

"button2来控制5个柱子让得到自己的值" 不太清楚这句的含义，你是不是想能单独控制每一个呢？
canvas.Children[index]应该就能得到你的5个柱子

追问

就是每一个柱子其实是一个array，然后那个array又random得到值。但是我现在是想用button2来画5个值。。。这个不会做。。。

追答

“想用button2来画5个值”这句，详细解释下

追问

哦 抱歉解释错误了。 就是用button2来画5个柱状图。 因为每个柱状图是一个sort。如果是用5个button来画5个柱状图很简单，就是用一个来画5个就不会了

追答

这5个柱状图的区别在哪个地方？从你的代码上看不出来。你需要用到Array的值来画么？
